What is the inside maximum width of a buckle on a belt in centimeters?

The inside maximum width of a buckle on a powerlifting belt is established to ensure that it meets the specifications set by the International Powerlifting Federation (IPF). The correct measurement, which is 11 centimeters, is crucial because it allows for compatibility with the rules governing equipment used in competitive powerlifting.

This specification is important for maintaining consistency and fairness across all competitors in the sport. If the buckle exceeds this width, it may not comply with the regulations and could potentially lead to disqualification. The 11 cm width strikes a balance between functionality—allowing the buckle to securely fasten the belt—and adherence to competitive standards set forth by the IPF.

In contrast, the other options either fall short of or exceed the allowance for acceptable buckle width, which could lead to issues during regulation compliance at competitions. Thus, knowing the correct internal buckle width is essential for lifters and officials alike in ensuring that equipment meets IPF standards.
